Fresh lemon juice has water, citric acid and phosphoric acid among its primary constituents. Actually, lemons have the highest citrate content levels, among any citrus fruits.

Many people claim that using fresh lemon juice for kidney stones is extremely effective for stones brought on by calcium crystallization. Lemon juice is naturally very acidic, and it is acidic properties are often credited for easier stone passage and prevention. The acid in fresh lemon juice may be able to help kidney stones either dissolve completely or become sufficiently small that they are able to pass with little pain. Using fresh lemon juice for kidney stones may also help to prevent the stones from forming since the acid can help prevent calcium crystallization, which generally leads to stone formation.

Lemon Juice for Kidney Stones

An individual who is interested in using lemon juice for kidney stone passage need to drink roughly 1 cup of pure fresh lemon juice dissolved into 1 quart water. Many people who believe in this process for kidney stone passage recommend drinking this mix at least twice in a 24-hour period. Rather than using water, some people advise mixing 2 ounces of fresh lemon juice with 2 ounces of essential olive oil three or four times a day before the stone passes. These methods aren’t guaranteed to work, and in the big event they are unsuccessful, a person should contact his doctor for help.

Why Fresh lemon juice for Kidney Stones?

Kidney stones can be created up of different chemical deposits in the human body. The most common is calcium oxalate, other medication is uric acid, cystine and struvite (magnesium, ammonium, phosphate). For those who have had kidney stones once, there is a pretty high chance they come again. So it is recommended to create changes in your diet and nutrition intake. The initial step is increasing fluid intake. Why should you drink more liquids? Whenever your liquid intake is less, or insufficient, urine remains in your body and becomes concentrated and acidic, enhancing the likelihood of kidney stones. But more fluids, means your urine gets disguarded and hence the symptoms of a kidney stone is reduced. So increased daily water consumption helps. A lesser known and equally efficient way is drinking lemon juice.

Fresh lemon juice has water, citric acid and phosphoric acid among its primary constituents. Actually, lemons have the highest citrate content levels, among any citrus fruits. Citrate is really a chemical that decreases acidity in urine and prevents kidney stone formation. Hence, upping your citrate levels, means bad news for existing kidney stones and cuts down on the risk of new ones. Lemon juice will help with increasing the amount of urine in your body, thus you pass more urine.


Kidney stones really are a common medical problem, and unfortunately when a kidney stone develops there’s increased risk that a different one will develop. Therefore, after the initial episode resolves the main focus turns to preventing further stone development. Kidney stones develop because certain substances within the urine reach a high enough concentration they form a solid.

Role of Citrate

Citrate works in multiple methods to prevent stone formation. First, it binds to calcium within the urine, and this prevents the calcium from having the ability to bind to other calcium within the urine, forming a stone. Second, if your stone has formed, citrate actually prevents more stones from forming. Within the December 1993 issue of the “Journal of Urology,” P. Barcelo, et al., are convinced that citrate supplementation raised the urinary citrate concentration in those studied and it is associated with a lower risk of recurrent stones in individuals with low urinary citrate before the oncoming of treatment.

Risk Factors

Certain characteristics of urine allow it to be more likely or less likely to create stones. A 24-hour urine test is essential to analyze these characteristics in order to figure out what risk factors are present. A urine that’s concentrated, contains too much calcium, oxalate, cysteine or the crystals, is infected with bacteria or either too acidic or too basic favors stone formation. Also, using a low concentration of citrate in the urine, under 320 mg/day, increases the likelihood of stone formation. It’s helpful to know the composition from the stone.

Using Lemon Juice

Citrate will come in several different prescription forms, but it’s also found in certain foods, particularly lemons. The prescription types of citrate are more effective than lemon juice at enhancing the citrate concentration in the urine. However, these medications aren’t always tolerated, and fresh lemon juice is an appropriate alternative. Within the September 1996 issue of the “Journal of Urology,” M.A. Seltzer, et al., are convinced that consuming 120 ml of lemon concentrate included 2 l of water each day worked well. The dilution not only aids in palatability but also increases the urine volume. Keep in mind that concentrated urine favors kidney stone formation.


Fresh lemon juice may be recommended by physicians to avoid stone recurrence. It is important to keep in mind that this is used in combination with balance diet changes and medicines, based upon the kind of kidney stone and also the risk profile determined by a 24-hour urine test.
